ATTACHMENT FOR MOTOR-VEHICLES.

Specification of Letters Patent.

Patented Ang. a, 19.15.

Application filed November 12, 1914. Serial No. 871,723,

To all whom it may concern:

, Be it known that I, JoriN B. Consnn, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Attachments for Motor-Vehicles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing and the characters of reference thereon.

This invention relates to improvements in motor-cycles, and has for its primary object the causing of the vehicle to function substantially as a cycle car without the addi-- tional weight or expense incident to the construction of the ordinary cycle car.

With this and further objects in View; as

will hereinafter in part be apparent and in part be stated, the invention comprises certain novel constructions, combinations and arrangements of parts as subsequently specified and claimed.

In the accompanying drawing :Figure 1 is a view in side elevation of a vehicle embodying the features of the present invention, the stay frame and wheel being shown in collapsed position. Fig. 2ris a top plan view thereof. Fig. 3 is a similar view with the stay frame and wheel extended in full lines and partially collapsed in dotted lines. Fig. i is an enlarged detail fragmentary section taken on the plane indicated by line H of Fig. 3 andlooking toward the main frame of the machine. Fig.5 is aperspective view of the part seen in Fig.- 4. Fig. 6 is an enlarged detail fragmentary cross section taken approximately on the plane indicated by line 6 6 of Fig. 1 and looking in the direction of the arrow. V Referring to the drawing by numerals, 1

indicates a main frame of a vehicle, which of wheel 3 and enable steering of the ma- 7 i chine. The post 7 is journaled in a portion of frame 1. The main body of the frame 1 consists of a pair of side bar-s spaced apart for a portion of their length andon which is mounted a car body 11-, provided with a seat 12, whichmay-be of various forms, but

preferably consists of an individual, cushloned seat adapted to accommodate the driver. Of course, an ordinary motor-cycle saddle could be employed but one of the features of advantage of the present improvement resides in enabling thense of a large, commodious seat for the user, which seat may be occupied by him while the vehicle is standing still as well as While running. 5

Preferably at the rear of the seat 12, a

cross bar 13 is fixed to the frame 1 and a brace or strap 14' is fixed to one end portion of thebar 13, the free end of the brace and connected by a bearing pin 16, surrounded by a bearing sleeve 17. Formed integral with or otherwise appropriately fixed to the 'the corresponding portion of the bar being sleeve 17 is a rod 18 extending at right anouter end bifurcated as indicated at 19. Between the arms of the bifurcation 19, is pivoted an axle 20, carrying a stay whee1'21,

- gles to the axis of the sleeve and having its the rod 18 and its cotiperating parts comprising a stay framefor enabling maintenance of the vehicle in upright position while stationary or moving, as will become apparent. An arm 22 is formed'in'tegral with or appropriately fixed to axle 'QOa-nd extendssubstantially at right angles to the longitudinal axis of the axle. The outer end of the arm 22 is pivotally engaged by a link 23, which is pivotally connected to an arm 24, formed integral with or fixedly carried by the bar 13 and extending substantially-at'right angles tothe main body of the bar, that is, extending along the main frame 1. The arms 22 and 2e are substantially equal in length so that the link23 lies approximately parallel withrod 18 and in' operation maintains substantial-parallelism therewith as indicated in dottedlines in Fig. 3 and in full lines in Fig. 2.

is a spring'plate'bracket 25;Wl1ich extends rearward and is providedafiits free end w th a substantial semi-circular recess or notch 26, adapted to receive the arm- 22 when the parts are folded, as indicated Figs. 6,.v

l and 2, whereby the pivot between link 23- j Fixed torod 18 Within' the bifurcation 19 r.

and arm' 22 is prevented from moving inwardly when the parts are collapsed asseen in Fig. 2, to a point beyond an alinement with the pivot between link 23 and arm 24. Such inward movement of the pivot between arm 22 and link 23 would arm is formed integral with or appropri-' ately fixed to the sleeve at one end and at the other end is pivoted to an operating link-28, which link extends forward along 20 frame 1 to a point near the front portion of seat 12 and there pivotally engages an operating lever'29.- The lever 29 is pivoted at 30 to the frame 1 and extends past a rack 31,- preferablyarcuate and provided with pawl receiving notches 32., A pawl 33 is carried by lever 29 and engages rack 31,

and anoperating grip 34c is pivoted to lever 29 and connected by a' link 35 with pawl 33 for enabling the operator when grasping the lever 29 to press the grip 34: and thus lift 'the pawl 33 and allow the lever 29 to be shifted for positioning the pawl in a forward or rearward-notch 32. It is obvious,

of course, that when the lever 29 is shifted to the extreme of rearward movement, the arm 27 will be advanced tothe forward extreme of its movement and therefore, will have caused rotation of sleeve 17 to an ex- .tent for swinging rod 18 to its-normal out- .standingposition substantially at right angles to the longitudinalaxis of the .main

frame of the machine.

To prevent any possible movement of arm 18 rearward be 'yond this normal position, a bracket 36 is V fixedto frame 1 in position for being struck by arm 27 at the extreme of its forward (movement, V

the rear of the seat121and is geared to drive wheel 2in the usual manner of an ordinary motor-cycle. I

7 when very low speed is desired. 7 What I claim is upward until the wheel 21, when the parts are completely collapsed, is clear of the ground and at a sufficient distance above the V lowered as it moves outward because of the incline of the axis on which the frame swings, until the wheel rests upon the ground as the arm 27 strikes-bracket 36 and. the wheel is inposition for carrying part of the load of the vehicle. The operator then releases his clutch or shifts his gear to neutral or stops his engine, and may then' re main seated since the vehicle is sustained in its upright position by the stay frame and It is obviousthat the stay or supplemental frame is essentially adapted to maintain the wheel 21 with its sides at all times parallel to the longitudinal vertical planes of the main frame, so that should the car be'tilted slightly to'one side while the supplemental frame is only partly extended, the wheel 21would be in position for operation. r The stay frame and wheel may be employed for sustaining the vehicle. in upright positionwhen stopping or starting when riding through muddy or rough j 1. ,In an attachment for, motor cycles, the combination with a frame, of a link pivoted roads or to a fixed part of the frame, a sleeve jour- 'naled on' the frame on an inclined axis and spaced from the pivot of said link, a rod fixed to the sleeve, an axle pivoted to the rod and having an arm pivotedto the link at a distance from the rod substantially equal to j the distance from the sleeve to the first mentioned pivot of the link, a wheel journaled on the axle'and means for imparting rotary p -movement to, the sleeve. not been illustrated but is mounted 1n the V 2'. an attachment for motor cycles, the combination, with a frame, of a link pivoted to arfixed part ofthe frame, a sleeve jourarm-pivoted .to the link at a distance from from the sleeve to thefirst mentioned pivot of thelink, a wheel journaled'on the axle,
